Carbohydrates have been demonised and framed as unhealthy for decades, but new research indicates there's some benefits in the mix too.

New research from University of Sydney suggests eating more of the right kinds of carbs could help people age better, and turn back the biological clock.

AUT Professor of Nutrition Caryn Zinn says this research was conducted well, but 'dietary cleanup' matters too.

"These groups cleaned up their diet, they ate more vegetables, they ate more fibre - so that will do it, that will make you live longer if you do dietary cleanup."
